About this opportunity
The General Services Administration Public Buildings Service National Capital Region published this Limited/Sole Source Justification Notice for Architectural/Engineering services to provide revisions to Issued for Construction drawings and Post Construction Award Services for B10 Vivarium Air Control Valves in Building 64. The contract was awarded to N.K. Bhandari Architecture & Engineer, P.C. on July 31, 2025, under contract number 47PM1125C0012, though the award amount was not disclosed. The sole source justification was based on NKB being the original designer of record with intimate knowledge of the project design, making them uniquely qualified to handle the complex modifications needed for the laboratory air valve installation and control system upgrades in the occupied building. The government posted the solicitation on SAM.gov on April 22, 2025, with responses due by May 7, 2025, but received interest from only one other potential vendor (LAND Engineering, PLC). The work involves installing laboratory air valves, implementing a new control system, and maintaining proper space pressurizations in the functional facility. The justification cites 41 U.S.C. 3304(a)(1) as statutory authority, asserting that NKB is the only responsible source capable of meeting the government's specialized requirements for this vivarium air control project.
